SEEDER ArjrAcrmmNT.

To all whom it may concern:

Be it known that I, J oiix WILLIAM HUNZE, a citizen of the United States, residingat Cape Girardeau, in the county of Cape Girar' dean and State of Missouri, have invented certain new and useful Improvements in Seeder Attachments; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the saine.

My invention relates to seeder attachments, and especially to devices which are ada )ted to mark the point of'dropping of the seed, so that equal rows may be formed entir-ely across the field to be planted.

Heretofore in numerous seeders it has been necessary to stretch a wire entirely across the field, and operate the seeder mechanism by knots or projections carried upon the Wire.

The mark mechanism here only consists of lugs or projections carried by the wheels, and

-friequeiitlyin turning it was difficult to get the seeder mechanism started properly, and to get the marks properly alined so that the rows would be even and symmetrical.

It is the object of my invention to obviate `these difficulties and irovide a device of this character which may e attached to an ordinary seeder so that it will finally discharge the seed at given points and simultaneously therewith mark the oint of discharge.-

A further obj ect oiJ the invention is the provision of means whereby the marker may be rendered inoperative upon turning curves or in going from one oiiit to another which it is not desired to p ant, and simultaneously throwing out of action the seeder mechanism. I also provide means for kee ing the marker en one wheel in alinement wit i the other, and means for adjusting the several parts to fit different sized wheels and different sized frames.

Further ob'ects of the invention will appear ss the speci c description which follows is read in connection with the accompanying drawings, in which k Figure 1 is a top plan view ofthe device, 2 is a sect-ion on the line 2-2 o f Fig. 1, sind Fig. 3 is asection on theline3-3 of Fig. 1.

Referring more especially to the drawings,

1l represents the frame, which is com osed of @de bars 2, end members 3, a longitudinal central member 4 and' an intermediate transverse member 5, which is secured to the side members 2 and the longitudinal member 4 by UNiTED STATEN JOHNWILLIAM HUNZE, OF` X .j Specification of L Patent.

v any suitable means.. Journaled in bearings A" in the-.side members`2 andin the rear end of the intermediate member 4 is the main supporting axle or shaft 6, upon which the usual supportingwheels 7 and 8 are carried. These wheels are\,keyed properly to the shaft, and the shaft revolves in the bearings within the j frame. Loosely mounted upon the shaft ad p jacent the side frame is a collar` 9, which is I provided withan annular groove l0 interme-A diate its length and adjacent its inner end is v a gear wheel 11.\1\ A similar collar 12 with an annular groove 13and a gear14 is secured upon the opposite side of` t-he shaft, and is provided with an extension arm 15, to which is secure an eye bolt 16 to be hereinafter describ d.

Keyed to the shaft adjacent the coll r 12 is a small ring 17, which is adapted to old` the shoe supporting band 18 in proper p i- 75 tion upon the axle. This shoe su )porting band 1S is provided with a )air of lugs pros, jected from its periphery, t 1e outer one of.\ which, 19, is adapted to receive a spiral k'\\` spring 20, which connects with the lug 21, carried upon the upper aim 22 of the marker i shoe 23. The upper arm 22 is adjustably mounted upon the lower arm 24, and is held I l in adjusted position by a set screw 25; The.V lower arm is )ivoted to the inner lug 26, and g5 c is connected y a link 27, secured to the eye bolt 16 upon the collar 12. Upon the op o- Q Y site side of the frame t-he collar 9 is provi ed Y with an annular groove 28, in which is secured a collar 29, formed in two halves and held together by set screws 30. Each part is provided with an operating paddle 31,

which engages the rocker arm 32 rotatably A.

mounted upon a stub shaft 33, carried by y i,

one of the side members 2 of the frame. The 95 end of this rocker arm is connected to a link 34, provided with a central turn buckle 35, to adjustiits length so that it may be regulated for different lengths of frames or machilies. The op osite end of the link is pivotally secure to the counter shaft 35',

which controls the mechanism in the seed boxes 36. Each collar 9 and 12 is rovided with a pair of axially alined para lel arms 37, which engage diametrically opposite 105 grooves 38, formed upon the band 18.

Secured to the rear end of the intermediate member 4 so as to overhang the axle 6 is a. bearing member 39 havin a socket 40, in which is journaled the sha t 41, up'on which 110 the crank arins 42 and the foot lever 43 is Y secured. To each one of these arms 42 I secure a link 43' divided into two parts con nectcd bv a turn buckle 44. The innerpart of the lilik 43 of that partadjacent the arms is provided with an oilset 45, which is adapt ed to take over-the shaft when the foot leveris in its lowerniost posit-ion, so as to lock the collais 9 and 12 in their retracted position as will be hereinafter described. The opposite ends of the links are passed through bearings in the side members of the frame and are attached to a pair of oppositely curved arms 46, which engage the annular recesses 10 and 13 of the collars 9 and 12.

In operation the spiral springs hold the shoes 23 in engagement with the periphery of the wheel and in suoli forcible engagement with the band 1S that the collars 9 and 12 travel around the axle and the collar 9 carries the seeder operating paddles so as to operate the rocker arm 32, and feed the seed from the seed boxes 36. ''Vhen the end of the row is reached and the operator wishes to turn t'lie machine around he presses down upon the foot lever 43 and thus re-tracts the collars 9 and 12 from their normal position. This action through the liiiks27 withdraws the shoes '23 from the wheels against the action of the spring 20, and at the saine time throws the paddles 31 out of the path of the rocker arm 32. By pressing the foot lever all the way down the alinenient of the links 43 pass the center of the sha-ft 4l, owing to the engagement of the offset portion 45 with the shaft thereby locking the collars in such osition until the operator inserts his foot beneath the lever 43, and releases it.' The spring pressure upon the shoes is sulicient to return the parts to normal and clamp the shoes against the wheel. In order to keep both shoes in alineiiient I extend across the frame a transverse shaft 47 with an elongated gear 4S on each end so as to mesh with the gears 11 Vand 14 in all-positions of their longitudinal movement upon the shaft 6.

Froni the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Yarious changes in the forni, proportion and the minor details ofl construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

Having thus described my invention what Y I claim and desire to secure by Letters-Patent is: y y

1. In a device of the class described, the

combination with a frame, a supporting axle ruiming therethrough, traction wheels mounted thereon, markers carried byV said axle, resilient means to hold said markers in engagement with the periphery of the wheelsl whereby they will rotate therewith, means for disengaging the markers and means to ad dinst the markers for different sized wheels.

2. In a device of the class described, the

combination with a frame of a su i oi'tin f y lP t axle therefor, tract-ion wheels upon said axle, markers carried loosely by said axle, a s ring .to hold said markers in engagement wit i the periphery of the wheels whereby they will be rotated with the wheels, means under control of the opera tor for releasing the markers from connection with the wheel, means for holding the markers in aliiienient and means to adjust the markers for different sized wheels.

In a device of the class described the combination with a frame. of a supporting axle therefor, traction wheels thereon, a pair of collars surrounding the shaft on either side of the frame, one of each pair being slidably mounted upon t-lie shaftand both being loosely mounted thereon, a pair of marker arms carried adj acent the traction wheels upon the collars, resilient means for holding the inaikers in engagement with the eri ery of the -wheel, means engaging the idalily mounted collars for operating the same, a link connection between the collars and the markers, a reci procal connection between the two collars, a connection between the reciprocal collars on either side of the frame for keeping the markeis in alinement and inea-ns to adjust the markers for different sized wheels.

4. In a device of the class described, a traction wheel, a marker, a spring for holding the marker in engagement with the traction wheel whereby it. Awill be rotated thereby and ineans'to adjust the markers for different sized wheels.

` 5.
